How to Extract Tin from Tin Oxide Ore?

Tin exists almost in the form of cassiterite (tin oxide) in the earth's crust. Its density is relatively large, so gravity separation is most used for tin extraction. In the pre-dressing stage of tin oxide ore, the common equipments are trammel screen, cyclones, rod mills and other equipment. Common equipment for gravity separation includes jig and shaking table.

How to Extract Tin from Tin Oxide Ore?

This post mainly introduces how to extract tin from tin oxide ore. Due to the high density of cassiterite (6.4~7.1g/cm3), gravity separation is often used to process cassiterite. However, cassiterite is easily sludged in the nature and in the process of ore sorting. Therefore, flotation is also used to recover fine-grained cassiterite from the fine mud and tailings. 1. Why is tin oxide ore ...
